Yes, probably. It shows a 37.3 percent rate of progression from prehypertension to frank hypertension reported in the Framingham Study after four years of follow-up.
In Germany as in all industrial nations, there is a continued rise of average life expectancy (Links). Therefore, I would not be concerned about normal blood pressures at 130/
From a prevention point of view, you should be very concerned. These persons may eventually develop hypertension and related complicatiobs if they do not receive an accurate education of lifestyle changes and future implications of borderline hypertension. In fact, I refer to it as "optional hypertension". You may also be more concerned if the patient is much younger, obese and has other risk factors for metabolic syndrome.

Thanks for the excellent question and challenge, with some highly intelligent contributions posted!
Having reviewed this issue, I would add my voice that the prodominant weight of the most robust critically appraised evidentiary base supports the imperative of addressing prehypertension to avoid adverse cardiovascular outcomes. Here's why, in brief:

THE EVIDENCE TO DATE:
THE CRITICAL NEED OF REMEDIATING PREHYPERTENSION
A meta-analysis of 25 RCTs [Thompson 2011], of 64,162 participants, demonstrated that patients with prehypertension who received antihypertensive medications had a significant reduction in the incidence of stroke, cardiovascular events (myocardial infarction and heart failure) and mortality compared with controls. And the recent meta-analysis of prehypertension and CKD [Li 2016] demonstrated meaningful evidence showing the increased risk of chronic kidney disease with elevations in blood pressure, with the RR of developing CKD being 1.28 times higher in patients with prehypertension than in individuals with normal blood pressure, thus supporting the significance of “prehypertension” for those individuals with BP values of 120-139/80-90 mmHg. These findings are cross-confirmed by a meta-analysis that included 1,003,793 participants from 6 cohort studies and concluded that the pooled RR of end-stage renal disease (ESRD) was 1.59 in prehypertensive subjects compared with those who had optimal BP values, after adjusting for age, sex, and ethnicity [Huang 2014].
In addition, two large clinical trials showed that both candesartan/Atacand (the TROPHY Trial [Julius 2006]) and ramipril/Altace (the PHARAO Trial [Luders 2008]) could reduce the incidence of hypertension by approximately 34% - 64%, and several studies regarding the clinical benefits of treating prehypertension in the US, Europe, and China, demonstrated positive outcomes including the prevention of hypertension, avoidance of target organ damage, or improvement of clinical outcomes [Fuchs 2015] including the PREVER trial [Fuchs 2011].

THE SIGNIFICANT LIMITATIONS OF JNC 8: HOW NOT TO DO GUIDELINES
Furthermore, I would not draw any conclusions from the omission of prehyperension in JNC 8: The JNC Panel failed to take into account data from several robust trials we have noted here in our review summary, and the Panel relied heavily - and rather disturbingly - on the JATOS Trial, which was only powered to detect an overly demanding 40% relative risk reduction in the primary end point, and VALISH Trial which manifestly had substantially fewer primary end point events than predicted), hence both not adequately powered, while at the same time ignoring in their data review, for instance the FEVER trial that clearly found a significant reduction in its primary composite end point among patients treated to below 140 mm Hg. Another study that did pre-specify a tight control goal of
